OK, so lets get some clean up going.
Flexiclamps … like all Barnack type cameras, you will need this tool
Remove single screw on the flash shoe. Slide out the metal spring plate. the hole on the bottom leads to a deep grub screw which you will loosen, then you can unscrew the PC socket.
Rewind knob … screw on the side loosen then pull off the knob, note that the inner plastic friction part may come out with it. Then ring nut which holds the body on that side … no notches so you have to use a flexiclamp to get that off.
The shutter speed dial is held on by three set screws. Loosen them then pull of the dial … in my case they were stuck so much that I had to drill them out, which you really do not want to do.
Last is the single screw by the shutter button.
Pull top off … the shutter button will fall out … underneath is another spring loaded button … and a washer.
Beware of the glass surfaces … some are silvered so they can be worn off by cleaning.
One thing that I noticed when I first received this camera was a loose film advance lever. You will see that there are three outter screws … but there are also three inner screws that are partially hidden by the spring, and a centre screw that all may need to be tightened. You can get at the inner ones without removing the spring, but it is better to unhook the spring from the inside to make more access.
Rangefinder Alignment
There are two large screws by the view/rangefinder ports. The right one is for the horizontal alignment with a simple screw turning … the left one, hmm, it is a wheel.
